Bioreleacide
Projet Win4collective Bioreleacide: (Formulations Bio-sourcées à relargage contrôlé et facilement adaptable d'agents phytosanitaires / BIO-based Capsules for the controlled RELEAse of pestiCIDE).
Type: Win4collective project (SPW-DG06)
Partners: Celabor, ULiège-Gembloux Agro-Bio Tech, CRA-W
Coordinator: Celabor
Duration: November 2024 - October 2026
The main objective of the Bioreleacide project is to develop bio-sourced formulations with different controlled release rates of plant protection agents. These systems will be based on mixtures of hydrophilic or hydrophobic nanocapsules and microcapsules, and their relative proportions in the encapsulated formulations will make it easy to adapt the release profile to the characteristics of the formulated PP (Plant Protection Products), the needs of the crop and the targeted bioaggressors. Several crop protection agents will be studied for encapsulation in these formulations:
- a synthetic root herbicide currently used as a CS formulation (capsule suspension, based on polymers derived from the petrochemical industry) ;
- a bioherbicide ;
- a fungicide based on plant extract;
- a synthetic insecticide.
The aim of the project is to develop a 100% biobased encapsulated formulation that is effective, safer and an alternative to current petrochemical-based CS formulations. The aim of the formulation developed will be to limit soil pollution by microplastics, limit the degradation of active substances, prolong their activity over time and ultimately reduce the quantity of plant protection products (PP) to be applied and/or the frequency of application (Celabor). In order to develop an effective formulation that respects both users and soil life, our project will study the release profile of innovative formulations for selected PPs in silico and under soil conditions, in comparison with conventional formulations (CRA-W U10). The impact of formulated phytosanitary agents on soil microbiota will also be studied, in comparison with conventional formulations (ULlège). Finally, the efficacy of formulated phytosanitary agents will be tested under controlled conditions (CRA-W U03)
In addition to these beneficial effects on the reduction of soil pollution, the project will have a significant direct or indirect impact on the mitigation of global warming, thanks in particular to the reduction in the use of petrosourced materials, the reduction in the quantity of phytosanitary products (PP) to be applied, and the facilitation of the transition to bio-sourced pesticides. The production of bio-sourced materials, notably from waste and/or by-products from the food, textile and forestry industries, for encapsulation and for crop protection products, generates lessCO2 than their petro-sourced equivalents.
